Definitions

  • the invention relates to a ceramic material and to powder produced therewith that can be used for ceramic layer systems.
  • Ceramics in general have a high thermal stability and are therefore often used as ceramic coatings on high-temperature components, such as turbines, especially gas turbines.
  • the constant aim is to improve the heat insulation properties of the ceramic material.
  • the object is achieved by means of a ceramic, a ceramic powder, and a system of layers as claimed.
  • Ceramic layers based on zirconium oxide with stabilizers are known; here, fully stabilized zirconium oxide is often used, owing to its better thermal stability.
  • the objective of the concept is to use partially stabilized zirconium oxide having an improved stability, especially thermal stability.
  • FIGS. 1 to 4 show exemplary embodiments of the invention.
  • the zirconium oxide is stabilized with 0.2 wt % to 8 wt %, more particularly with 0.2 wt % to 6.0 wt %, of base stabilizers: yttrium oxide, hafnium oxide, cerium oxide, calcium oxide and/or magnesium oxide and optionally with additional stabilizers— 0.2 wt % to 20 wt % of erbium oxide and/or ytterbium oxide.
  • Yttrium oxide is used in any case and at least one of the base stabilizers hafnium oxide, cerium oxide, calcium oxide and/or magnesium oxide is used.
  • This ceramic composition may be prepared as a powder, and so further additions, as in the use of abrasive layers, comprise cubic boron nitride or other abrasive particles.
  • the ceramic layer of the ceramic material in accordance with the invention may be produced by means of EB-PVD, plasma spraying (APS, etc.), etc. and has a columnar structure or a segmented structure.
  • the layer 10 I , 10 ′′, 10 ′′′, 10 IV ( FIGS. 2-4 ) preferably has a layer thickness of 100 ⁇ m to 1000 ⁇ m.
  • a ceramic layer 10 II as in FIG. 1 may also have a ceramic sublayer 13 II , the layer thickness of which, however, is at least 20% thinner in configuration than that of the ceramic material of the invention in the ceramic layer 10 II .
  • the ceramic sublayer 13 II preferably comprises 8YSZ, i.e., zirconium oxide stabilized with 3 mol % to 4 mol % of yttrium, and is therefore distinctly different from the material of the ceramic layer 10 II .
  • FIGS. 3 and 4 show further examples of layer structures 1 III , 1 IV of the invention.
  • FIG. 3 in comparison to FIG. 1 , there is a segmented ceramic layer 10 III of a layer system 1 III , which comprises numerous, relatively long and vertical cracks 15 , 15 I , starting from the surface 18 of the outermost ceramic layer 10 III , and extending very largely over the entire ceramic layer thickness, here in particular up to the metallic adhesion layer 7 or the TGO thereof (not shown).
  • a layer system 1 IV may also comprise a ceramic attachment layer 13 IV ( FIG. 4 ) for the outermost TBC 10 IV , in which case the attachment layer 13 IV may be configured as described in FIG. 2 .
  • the outermost ceramic layer 10 IV is more particularly configured like the outermost layer 10 III in FIG. 3 .
  • cracks 14 extend, preferably likewise vertical, which extend through both ceramic layers 10 IV , 13 IV .
  • the relatively long cracks have been formed by specific process parameters or production methods, and do not represent cracks between multiple grains.
  • the ceramic material comprises preferably 2.5 wt % to 5.5 wt % of yttrium oxide (Y 2 O 3 ), more particularly 3.0 wt % to 5.0 wt % of yttrium oxide (Y 2 O 3 ), especially 3.5 wt % to 4.0 wt %.
  • the ceramic material may also comprise preferably 1.5 wt % to 3.0 wt % of yttrium oxide (Y 2 O 3 ), more particularly 2.0 wt % to 2.5 wt % of yttrium oxide (Y 2 O 3 ).
  • the ceramic material preferably comprises: hafnium oxide (HfO 2 ) at 0.2 wt % to 4.0 wt %, more particularly 0.5 wt % to 4.0 wt % of hafnium oxide (HfO 2 ), especially 0.6 wt % to 4.0 wt % of hafnium oxide (HfO 2 ).
  • the ceramic material preferably comprises: hafnium oxide (HfO 2 ) at 0.2 wt % to 2.0 wt %, more particularly at 0.6 wt % to 2.0 wt % of hafnium oxide (HfO 2 ), especially at 0.8 wt % to 2.0 wt % of hafnium oxide (HfO 2 ).
  • the ceramic material preferably comprises: hafnium oxide (HfO 2 ) at 2.0 wt % to 4.0 wt %, more particularly 2.4 wt % to 4.0 wt % of hafnium oxide (HfO 2 ), especially 4.0 wt % to 4.0 wt % of hafnium oxide (HfO 2 ).
  • the ceramic material preferably comprises 5.5 wt % to 8.5 wt % of ytterbium oxide (Yb 2 O 3 ), more particularly 6.0 wt % to 8.0 wt % of Yb 2 O 3 , especially 6.5 wt % to 7.5 wt % of Yb 2 O 3 .
  • the ceramic material comprises preferably 3.0 wt % to 4.5 wt % of ytterbium oxide (Yb 2 O 3 ), more particularly 3.5 wt % to 4.0 wt % of ytterbium oxide (Yb 2 O 3 ).
  • the ceramic material also preferably comprises 2.0 wt % to 4.0 wt % of Er 2 O 3 , more particularly 2.5 wt % to 3.5 wt % of Er 2 O 3 .
  • the ceramic material comprises (6.0-x) wt % of Y 2 O 3 +(2-4) x wt % of Yb 2 O 3 /Er 2 O 3 , i.e., at 4.0 wt % of Y 2 O 3 , x corresponds to 2 and the fraction of Yb 2 O 3 /Er 2 O 3 is (2-4)* 2 , i.e., between 4 wt % and 8 wt %.

Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application is the US National Stage of International Application No. PCT/EP2020/057029 filed 18 Mar. 2020, and claims the benefit thereof. The International Application claims the benefit of German Application No. DE 10 2019 217 445.0 filed 12 Nov. 2019. All of the applications are incorporated by reference herein in their entirety.
    • FIELD OF INVENTION
  • The invention relates to a ceramic material and to powder produced therewith that can be used for ceramic layer systems.
    • BACKGROUND OF INVENTION
  • Ceramics in general have a high thermal stability and are therefore often used as ceramic coatings on high-temperature components, such as turbines, especially gas turbines.
  • The constant aim is to improve the heat insulation properties of the ceramic material.
    • SUMMARY OF INVENTION
  • It is therefore an object of the invention to solve the problem identified above.
  • The object is achieved by means of a ceramic, a ceramic powder, and a system of layers as claimed.
  • Ceramic layers based on zirconium oxide with stabilizers are known; here, fully stabilized zirconium oxide is often used, owing to its better thermal stability.
  • The objective of the concept, however, is to use partially stabilized zirconium oxide having an improved stability, especially thermal stability.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIGS. 1 to 4 show exemplary embodiments of the invention.
    •  DETAILED DESCRIPTION OF INVENTION
  • The zirconium oxide is stabilized with 0.2 wt % to 8 wt %, more particularly with 0.2 wt % to 6.0 wt %, of base stabilizers: yttrium oxide, hafnium oxide, cerium oxide, calcium oxide and/or magnesium oxide and optionally with additional stabilizers— 0.2 wt % to 20 wt % of erbium oxide and/or ytterbium oxide.
  • Yttrium oxide is used in any case and at least one of the base stabilizers hafnium oxide, cerium oxide, calcium oxide and/or magnesium oxide is used.
  • This ceramic composition may be prepared as a powder, and so further additions, as in the use of abrasive layers, comprise cubic boron nitride or other abrasive particles.
  • In a layer system 1 I (FIG. 1) a ceramic layer 10 I is applied to metal, the substrate 4 present, in the case of nickel- or cobalt-based superalloys used preferably, being a metallic adhesion layer 7 which forms aluminum oxide (TGO; not shown), with the metallic adhesion promoter layer constituting preferably an aluminide, platinum-aluminide or, as a basis, an NiCoCrAlY alloy, optionally with x=Ta, Re, Fe and/or Si.
  • The ceramic layer of the ceramic material in accordance with the invention may be produced by means of EB-PVD, plasma spraying (APS, etc.), etc. and has a columnar structure or a segmented structure.
  • The layer 10 I, 10″, 10′″, 10 IV (FIGS. 2-4) preferably has a layer thickness of 100 μm to 1000 μm.
  • As shown in FIG. 2, a ceramic layer 10 II as in FIG. 1 may also have a ceramic sublayer 13 II, the layer thickness of which, however, is at least 20% thinner in configuration than that of the ceramic material of the invention in the ceramic layer 10 II.
  • The ceramic sublayer 13 II preferably comprises 8YSZ, i.e., zirconium oxide stabilized with 3 mol % to 4 mol % of yttrium, and is therefore distinctly different from the material of the ceramic layer 10 II.
  • FIGS. 3 and 4 show further examples of layer structures 1 III, 1 IV of the invention.
  • According to FIG. 3, in comparison to FIG. 1, there is a segmented ceramic layer 10 III of a layer system 1 III, which comprises numerous, relatively long and vertical cracks 15, 15 I, starting from the surface 18 of the outermost ceramic layer 10 III, and extending very largely over the entire ceramic layer thickness, here in particular up to the metallic adhesion layer 7 or the TGO thereof (not shown).
  • A layer system 1 IV may also comprise a ceramic attachment layer 13 IV (FIG. 4) for the outermost TBC 10 IV, in which case the attachment layer 13 IV may be configured as described in FIG. 2.
  • The outermost ceramic layer 10 IV is more particularly configured like the outermost layer 10 III in FIG. 3.
  • In the ceramic attachment layer 13 IV, however, cracks 14 extend, preferably likewise vertical, which extend through both ceramic layers 10 IV, 13 IV.
  • The relatively long cracks have been formed by specific process parameters or production methods, and do not represent cracks between multiple grains.
